CARD HOLDER.

Application led yApi-i1 22, 1922. Serial No. 555,935.

To all whom #may concern:

Be it known that I, CLARENCE I. BAKER, a citizen of the United States, residing at Elizabeth, in the county of Union, State of New Jersey, have invented certain new and useful Improvements in Card Holders, of which the following is a full, clear, concise, and exact description.

This invention relates to a card holder which may be quickly and securely mounted.

An object of the invention is to provide a clamping means for a card holding frame of such a nature that the clamping means will be concealed by the frame when the latter is mounted. It is proposed, however, that this means should be so constructed that the frame may be easily removed by a person understanding the mounting thereof, in order that the information cards therein may be readily changed or removed.

The form of this invention hereinafter described in detail, comprises a clamping plate and a cup-shaped frame between which the card to be held is inserted. The clamping plate is provided with outwardly extending irregularly shaped wings which cooperate with projections on the cupshaped member in such a manner that when the frame is placed upon the plate and rotated through a small angle, the frame is held tightly against the plate and thereafter rotation of the frame in either direction is prevented. In order to release the frame, it is necessary vto pry the frame upwards so that 'certain projections on the frame are clear of the outwardly extending wings of the plate.

In the drawings:

Fig. 1 shows a telephone dial having attached thereto the improved clamping plate, the card holder being offset to show its relation to the plate.

Fig. 2 is a face View of the clamping plate;

Fig. 3 is a view of the card holder partly in section.

Fig. 4 shows the card holder in side elevation.

Referring to the drawings more in detail, a cup-shaped frame or card holder 1 is provided with a downwardly projecting tongue 2, and inwardly projecting lugs 3, 4 and 5. A'transparent disc 6, an instruction card 7 and a metal securing plate 8 are adapted to t under the lugs of said cup-shaped frame,

and are each provided with a notch 9, the sides of which cooperate with the down wardly projecting tongue 2 to hold the discs against rotation. In this manner, the card is held in one angular position.

A clamping plate 10 may he secured to any desired surface, being shown inthe drawings as attached to the finger plate 11 of an automatic telephone dial by means of a dial assembling nut 12. (This dial may be of the type disclosed in U. S. Patent 1,161,854 to O. F. Forsberg, November 30, 1915). The clamping plate 10 is provided with outwardly extending flanges or wings 13, 14 and'15, which cooperate with the lugs 3, 4 and 5 respectively, to hold the cupshaped frame upon the clamping plate. These flanges are provided with a flared edge 16, in order that the lugs may more readily engage the under surfaces thereof during the rotation of the card frame, and are provided with camined surfac 17 which give a wedging action to the lugs as the frame is rotated, thereby securely kholding the frame to the finger plate.

A tang18 integral with clamping plate 10 projects downwardly into a hole 19 in the finger plate 11 to hold the clamping plate 10 against rotation. Extending laterally from the tang 18 and integral therewith is an inclined surface 20 which serves as a track or guide forv an inwardly projecting locking tongue 21 on the cup-shaped frame or card holder 1. In attaching the frame 1 to the finger plate 11, it is. so placed over the clamping plate 10 that the notches 3, 4 andv 5 fall within the spaces between the flanges or wings 13, 14, and 15. Downwardly projecting tongue 2 is placed in the space between the wings 13 and 15, and inwardly projecting tongue 21 is placed in the` space between the wing 13 and the lower edge of inclined surface 20. The frame is now rotated in a countencloclrwise direction causing the lugs to be wedged `under the flanges of the clamping member and causing lock ing finger 21 to ride up over the inclined surface 2O and to drop off from the 4high end of the inclined surface adjacent fla-nge 14. In this position, locking tongue 21 engages tang 18 and prevents clockwise rotation of the card holder from releasing the same. During the counter-clockwise rotation of the card holder the downwardly projecting tongue 2 travels from the edge of flange 15 llU to the adjacent edge of flange 18 (Fig. 2), coming into engagement with flange 13, just 4as locking tongue 21 drops over the edge of the inclined surface 20. The engagement of doaf'nwardly projecting tongue 2 and the iange 13 in this advanced position prevents further counter-clockwise rotation of the frame 1. Locking tongue 21 and downwardly projecting tongue 2 may therefore be seen to lock the frame on card holder 1 against rotation in either` direction.

In order to release the fra-me, it is necessary to pry the frame upwards so as to permit locking tongue 21 (Fig. 3) to clear the high edge of inclined surface20 and to simultaneously rotate the card holder in a clockwiseI direction.

Although specific card holder and clamping plate have been described, it is to be understood that this invention is not limited to the modilication disclosed, but is likewise applicable to other forms of card holders and clamping plates with locking means for securely attaching a trame thereto.

The invention claimed is:

1. In combination, a calling dial comprising a linger wheel and a card holder therefor comprising a resilient clamping plate secured to the linger wheel, and a cup-shaped frame held to the calling dial by said clamping plate and locked thereon by said plate against removal.

2. A card holder comprising a body portion, a resilient clamping plate secured thereto, a cup-shaped frame held to the body portion by the clamping plate and means to completely prevent the rotation of the cupshaped member upon the body portion.

3. A card holder comprising a body portion, a resilient vclamping plate mounted thereon having spaced wings and a locating tang on its periphery, a cup-shaped frame having inwardly projecting lugs adapted to engage said wings to be held thereby aga-inst the body portion, and having an inwardly projecting member for engaging said tang to hold said frame against removal.

4. In combination a plurality of discs, a cup-shaped trame having inwardly pro-jecting lugs and tongues for securely holding said discs within said frame and aga-inst rotation, a body portion, a clamping member attached to said body portion and having peripheral wings with uneven surfaces for engaging the inwardly projecting lugs on said frame to securely hold said iframe against said body portion, and -an inclined surface integral with said clamping member and cooperating with one of the tongues of said cup-shaped frame to `lock said yframe against. rotation. l

5. In combination, a plurality of discs, a cup-shaped frame for securely holding said discs therein against rotation, said frame having inwardly projecting lugs and being provided with tongues, a body portion, a clamping member secured to said body portion and provided with peripheral wings for engaging said inwardly projecting lugs to hold said frame upon said body portion, and an additional wing serving to guide one of said tongues into position to engage one edge of the wing, the other of said tongues being rotated in a position to engage one of said first named wings, said tongues cooperating to lock the cup-shaped frame against removal.

6. In combination, a calling dial, a resilient clamping plate mounted thereon and having wings on .its periphery, a cup-shaped frame having inwardly projecting lugs yadapted to be engaged' by said wings and to be held thereby to said calling dial, a card held within said frame, means Jfor holding said frame against rotation when mounted on the clamping plate, and means for holding said card against rotation within the frame.

In witness whereof, I hereunto subscribe my name this 18th day of April A. D., 1922.

CLARENCE I. BAKER.
